PRODUKTIVITAS PRIMER DANAU LAIT KECAMATAN TAYAN HILIR DITINJAU DARI KELIMPAHAN DAN KANDUNGAN KLOROFIL-A FITOPLANKTON
ABSTRACT: The phytoplankton is
one of the producers on waters that have capability of photosynthesis and can
be used to determine the level of the primary productivity on waters. This
research aims to determine the primary productivity and the fertility level of
the Lait Lake based on the abundance and content of phytoplankton
chlorophyll-a. In this research, the method used was purposive sampling and the
data analysis used was Pearson correlation. The results of the research found
48 genera of phytoplankton comprises 33 genera of Chlorophyta, 8 genera of
Chrysophyta, 3 genera of Euglenophyta, 3 genera of Cyanophyta, and 1 genera of
Phyrrophyta. The Phytoplankton of the Chrysophyta division has the highest
abundance (1957.44 ind / L), but the quantity of genera found was fewer. The
abundance of phytoplankton on waters Lait Lake ranged from 998.40 to 6609.29
ind/L with chlorophyll-a ranged from 0.05 to 0.20 mg/m3, and therefore the Lait
Lake categorized as water with low fertility level (oligotrophic).
